- Which is the correct statement of ultrasound preparation for the skin examination?
- High-frequency apparatus, at least 10MHz, is appropriate for detailed skin observation.
- Elastography could be applied for the examination of skin stiffness.
- Linear probe is a better choice for scanning.
- All are correct.
- Which is the correct statement of the sonographic finding of psoriatic skin?
- The epidermis appears as a continuous hyperechoic line, with increase thickness.
- A hypoechoic band could be observed between epidermis and dermis.
- Both (A) and (B) are correct.
- Both (A) and (B) are incorrect.
- Which is the correct statement of the sonographic finding of scleroderma?
- Increase thickness at both epidermis and dermis.
- Elastography is beneficial for diagnosis.
- skin thickness and stiffness are associated with scleroderma disease activity.
- All are correct.
- Ultrasound is helpful for the differential diagnosis between psoriatic arthritis (PsA) and rheumatoid arthritis (RA). Which of the sonographic finding is correct?
- RA may reveal bone erosion, but PsA dose not.
- PsA may reveal synovial hypertrophy, but RA dose not.
- PsA may involve entheses.
- PsA dose not involve tendon.
- What is true about the definition of sonographic anomalies in rheumatoid synovitis?
- Presence of hypoechoic synovial hypertrophy.
- Presence of joint effusion.
- Presence of increased power Doppler signal.
- Presence of bone erosions.
- What is true about the definition of sonographic anomalies in rheumatoid tenosynovitis?
- Presence of hypoechoic or anechoic thickened tissue within the tendon sheath.
- Presence of fluid within the tendon sheath.
- Presence of Doppler signal within the tendon sheath.
- Presence of retraction sign within the tendon sheath.
- What is true about the application of musculoskeletal ultrasound in rheumatoid arthritis (RA)?
- Musculoskeletal ultrasound can detect anatomical change but no evidence to guide therapeutic response for RA.
- The clinical examination is more sensitive than musculoskeletal ultrasound to detect synovitis and tenosynovitis in RA.
- Musculoskeletal ultrasound has strong evidence superior than clinical examination in detection of inflammation and evaluation of disease activity for RA.
- Because the clinical remission for RA is hardly achievable so the therapeutic response guided by ultrasound is not recommended.
- What is true about the application of semiquantitative scoring system in rheumatoid arthritis (RA)?
- For rheumatoid synovitis the greyscale and Doppler finding was evaluated together.
- For rheumatoid tenosynovitis the greyscale score is more reliable than Doppler score.
- For rheumatoid tenosynovitis, the aim to check two perpendicular planes is to obtain better Doppler signals.
- Provide strong evidence for rheumatologist to follow up tight control in RA.
- The diagnosis of malrotation, with an emphasis on the relationship of the SMV and SMA and the so-called “whirlpool sign”. Which is correct?
- SMV is located to the right anterior of SMA.
- SMV is located to the right lower of SMA.
- SMV is located to the left lower of SMA.
- SMV is located to the left anterior of SMA.
- The differential diagnosis for small bowel obstruction in neonates includes:
- Duodenal atresia.
- Malrotation and volvulus.
- Jejunoileal atresia.
- Meconium ileus and meconium peritonitis.
- All of the above.
